Off a 2008 GS I bought a while back. Tires are used but not worn out. I just hate Michelin tire. Tried them many times over the years with same results. When I raced I was 2-3 seconds faster a lap on Dunlops. Michelins want to tuck the front end all the time, fight with the geometry of the bike. Dunlops were very neutral and I could slide the bike with confidence and the front end would not tuck, even under hard braking. I tucked the front end on these michelins and put the GS down, broke a few ribs too. I knew it might happen but I was playing with the bad handling and my luck ran out. I mean who want to let a set of bad tires kick your butt? Put on a set of Shinko's 705 rear and 805 front. WOW what a difference. The bike is back to neutral handling and feels great. Have not even had it off road yet......probably tomorrow...sore ribs or not.
